IMPOVBMENT IN WATER-METERS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may con-cern:

it known that I, JOSEPH lF. KELLEY, of Washington city, in the District O f Columbia, have invented certainnew and useful Improvements in Water-Meters; .and I do hereby declare that `the following is a 'tulh'eleau'and exact description thereof, reference be- 'ing had to the accompanying drawings which make part ot this specification, and in which- Figure l represents an elevation of a water-meter,

embracing my improvements.

Figure 2 represents a part-iai sectional View of the -tubing'ot'the meter, showing the .driving-screw of the registering mechanism.

Figure 3 is an elevation of the screw detached from the water-tube, constructed with vanes or ribs.

Figure 4; represents the ratchet and spring, for preventing any retrograde movement of the registering mechanism.

s Figure '5 represents a face view ofthe dial and indexvbands.

In the accompanying drawings the ltubing of the meter consists of three sections: a T-shaped egress section, A, upon which the registering mechanism is mounted and supported; a curved ingress section, C;

and an intermediate straight coupling section, B, having c ut uports extremities screw-threads, for the purpose of connecting the end sections A C.

Within the intermediate tube B a screw, E, is arranged, the aXial shaft o f which is supported in bearings in a cross-bar, li, at the rear end of said tube, and at m, in the front side of the T; shaped section A.

The end of the axial sb'aft projects through and beyond the T- shaped section to receive a pinion, k,'whieh engages wlth suitable registering mechanism.

The supporting cross-bar h serves also as a break,

-to interrupt the continuity of the water at the entrance while its worm perfectly lls the tube, so that the water cannot escape through itexcept over the driv ing surfaces of the screw.

The screw isprovided on its driving or inner surface with smaller flangesor buckets, a, placed on the aot-- .ing or driving surface of the screw at proper intervals throughout its length, for the purpose of acting as stops to the gliding passage oi' the water, to agitate or rule it, thereby rendering absolutely cert-ain the action oi' the screw, whatever may be the't'orce ot' the iiow of water against it, as it frequently happens that the water passes over and through the screw without tuin,-

`ing it sulciently to register the full amount of water which has Apassed through. These iiangs or buckets have only suliicient projection li'om the surface ofthe screw to produce the result abovestatetbf and cannot, therefore, materiallyretard the passage of the water, while a perfect action ot' the screw is obtained.

The upper end of the T- shaped egress section A is tted with a screw-tap, b, which may be removed, when necessary, to afford facility for cleaning out the tube.

The registering. mechanism is supported upon and secured directly to this section of tube A by means ot' a screw, d, pas seal through t-he heid ot the s :row-tap b into the fra-me of said mechanism, anda bracket, c, bolted to the lower end of said section and to the bottom ofthe said frame.

By means of this attachment the meter is rendered very-compact, and the whole mechanism can -be rit-ted and supported within a box a very little larger than the diameter of the 'dial-plate; and itcan be readily removed from the tubing for repairs, or to be replaced by any ot-lier suitable mechanism.

The axial sliaft'of the screwis provided with a ratchletremovable screw-tap b, by which the attachment and support of the registeringmechanism is rendered compact, its removal and replacement eiiected with facility,

and admitting ofthe cleaning out of the tube when clogged, in the manner Aherein shown and described. JOS. F. KELLEY.
